Green Monstah Firearms

Richie opened Green Monstah Firearms on July 24, 2021, after retiring and deciding to pursue something closer to her calling. In business since 2014, she brought her expertise to Martinsburg, WV and created more than just a retail store—a genuine community hub where shooters of all skill levels feel welcome.

Green Monstah isn't built on corporate speak—Richie's approach is treating customers like family and growing together as a community. The shop welcomes pets and families, maintains reasonable pricing on high-quality products, and actively gives back locally. Whether you're building your first AR, trading in used firearms, getting a gunsmith repair done, or taking professional training, they handle it with the same attention to detail. That's the difference between a transaction and a relationship.
